Want to Buy Vivitar Bellows Part

[binglebugbob]

I need the threaded round disk (T thread) for the front of a Vivitar Universal Bellows. This is the threaded plate that a female T adapter (allowing use of a standard camera mount lens.)
The threaded round plate is held in place on the front of a Vivitar bellows with 2 locking chrome thumb screws.
I DON'T need or want the common male threaded adapter (to adapt a T mount lens to a camera). I have most of the other Vivitar bellows accessories (macro stand, focus rail etc.)
As it is, I have no way to mount a lens on the front of the be(llows.

I have several female T adapters, but not the threaded disk they screw into.
Would consider a "junker" bellows having the threaded front plate.
Thanks for looking.
Bob.

I am a bit confused as to what you actually need. A photo of where the missing part goes might help. I used to sell the Vivitar bellows system when they came out in the mid-70's, thought they were a very neat idea. You could use several brand lenses on your camera for macro work. I did purchase several of the lens mount rings and still use them with the camera body t-mount for close-up work. The lens mount rings are quite difficult to find, most people have no idea what they are used for since "t-mount" is an ancient system. Good luck, RB

I agree, it was a great system for those people having 2 or 3 different camera systems. I know Canon made a spring loaded adapter so that the bellows could make use of the Canon auto diaphragm. via a double release cable. I suspect other manufacturers also made a similar device.

I have several female T lens mounts and several more common male T mounts for the rear of the bellows.

I was writing from memory because my bellows is in a storage warehouse at the moment, but I see that there is only one satin chrome thumb screw on the front standard that locks the black painted disk onto the front standard--not two. Loosening the thumb screw allows the disk to be turned that the aperture scale on the lens can be seen easily. Without the disk there is just an opening with nothing to screw the lens adapter into. The disk resembles the lens disk on an old Omega D2 enlarger.

If you have the disk, I could also use a couple of the original satin chrome thumb screws, if you had them.

If I haven't clarified this, let me know and I'll dig my bellows out of my storage unit this weekend and photograph it.
